I know the weather still sucks here, but keep us posted on your thoughts as you put some miles on your car. Nice talking with you last night.

I just got my K1 tune back, and haven't dyno'd but am impressed. In sport mode auto, i hit the rev limiter in 1st gear...first that that has happened (at least where I wasn't shifting). This happened while I was running against a crotch rocket...greatest thing in the world was he could hear me, but he couldn't see me because I was keeping right next to him
...he kept flipping his head around both sides of the bike trying to find me. We hit 3 digits and I let off..but I had pulled a length on him from where I started, and I felt the car much strong top end...it pulled pretty hard for sure...I was impressed 
We'll see what the dyno says this pm.

i was able to test the tune out some this weekend. i put a lot of highway miles on it, but i could definitely tell a difference. the first time i floored it in 3rd gear, the speedo climbed a lot faster than before. and i could feel myself get pulled back more than i used to. pretty awesome. i'll be doing more testing in the future. i've raced a friends e46 m3 stock and i could beat it fairly easily, but he's one of few cars i've raced when i was stock. so maybe i can see how much more i can beat him by.
i've also got an out of town friend with a stock E55 that i also raced when stock, and now i can't wait to race again to see how i do

It is hard to get an exact number, since dynos are different as well.
But I got 370whp and divided by .82 (18% drivetrain loss) and got 451bhp...recommend using a number that gets you to 451 from your first go (so 352.5 would use 22% drivetrain loss which would give you 452bhp...take 352.5 and divide by .78).
Then, take that number for your afters: 387.5whp (based on your 35whp increase you noted), and that gives you 387.5/.78 = 496.8bhp...NOT BAD!

Bluejae...that is a drivetrain calculation...easiest way is to take your stock numbers and divide by like .82 or .80, depending on how much drivetrain lost you expect.
